MiniMax: the model is MiniMax-M3.1-Flash (out of preview)

The API now answers MiniMax-M3.1-Flash-Preview as MiniMax-M3.1-Flash, and
accepts the new name directly. Verified 2026-11-03: a live call returns
"ok" with a 1M context window. Claude Code 2.1.317 prints an
unrecognized_model warning for either name; the session still runs.
